Docking Station/Hub — OEM / ODM Manufacturer

What we manufacture

Dongguan Taitron Electronic Limited (brand Tonetron) manufactures 20 hub and docking adapter models in its own 50,000 square meter factory in Dongguan, China. Established in 1984 in Keelung, Taiwan, it employs 300+ people and exports to 40+ countries. We have been an HDMI Adopter for 20 years. Our USB4 Gen3 Type-C cable passed USB-IF certification testing in 2022 (Test ID 6801); our USB-IF membership has since lapsed, so it no longer appears in USB-IF's public product search.

The catalog runs from a USB-A 4-in-1 hub (MP300, three USB 2.0 ports plus 100 Mbps Ethernet) to USB-C 7-in-1 modular adapters (PF434A). Between those sit five classes: pure port expanders with three or four USB 3.0 Type-A ports at 5 Gbps (MP464, MP462, PF414A); network adapters at 100 Mbps or Gigabit (MP420, PF412); single-video adapters with HDMI or VGA plus one USB 3.0 port (PF502, PF503, MP459, MP438); 5-in-1 and 6-in-1 hubs that combine HDMI with USB-A, Gigabit Ethernet, SD/TF readers or a 5 Gbps USB-C data port (PLT465, MP461GR, MP468GR, PF423A, PF459, WG508A, WG508B, WG608A); and modular 6-in-1 and 7-in-1 adapters with plug-in card reader and RJ45 modules (PF433A, PF434A).

Video output on current models is HDMI at 4K 30 Hz on most hubs, HDMI at 4K 60 Hz on the PF503, and VGA at 1080p 60 Hz on the MP438. USB PD pass-through is 60 W on every model that carries it, with PD 3.0 on the PF423A and PF414A. Housings are grey aluminum, zinc alloy with a mirror face (WG508A, WG508B, WG608A), or a leather push-cover with phone-holder function (PF459). Cables are attached pigtails; the PF502 and PF503 use nylon-braided cable with reinforced strain relief. A detachable-cable housing is a tooling change and should be stated in the RFQ.

Compatibility notes buyers must specify

The host port decides what a hub can do. Video over USB-C requires DisplayPort Alt Mode on the host. A hub with an HDMI port plugged into a USB-C port that only carries data and charging will deliver the USB and PD functions and no picture. Confirm the laptop fleet supports DP Alt Mode before specifying a video-capable model; if it does not, a DisplayLink-based design is the alternative, with a different controller, driver and price.

Resolution and refresh follow the signal path. 4K 60 Hz over HDMI requires an HDMI 2.0-class path at 18 Gbps from the host through the hub controller to the port; 4K 120 Hz requires 48 Gbps. On this line, 4K 60 Hz is available on the PF503 and 4K 30 Hz on the other HDMI models. The MP438 outputs VGA at 1080p 60 Hz for projector rooms.

Single display only. Every current model drives one external display. Dual-display docks, MST or USB4-class bandwidth are outside the standard catalog; USB4 hosts can drive higher-bandwidth docks, but gain nothing from a 5 Gbps hub beyond backward compatibility.

PD pass-through is a budget, not a promise. The 60 W input on these hubs feeds the host laptop after the hub's own draw; a laptop that needs more than that under load will charge slowly. USB PD pass-through up to 100 W is common in the market and can be quoted as a custom build.
